# Phase 07 — Validation Strategy

> Per-phase validation contract for feedback sampling during execution.

---

## Test Infrastructure

| Property | Value |
|----------|-------|
| **Framework** | Vitest + Playwright（frontend） |
| **Config file** | `frontend/vitest.config.ts`, `frontend/playwright.config.ts` |
| **Quick run command** | `cd frontend && pnpm -s test -- --run src/core/threads` |
| **Full suite command** | `cd frontend && pnpm -s lint && pnpm -s typecheck && pnpm -s test:e2e --grep "input|compose|mention"` |
| **Estimated runtime** | ~240 seconds |

---

## Sampling Rate

- **After every task commit:** Run `cd frontend && pnpm -s test -- --run src/core/threads`
- **After every plan wave:** Run `cd frontend && pnpm -s lint && pnpm -s typecheck`
- **Before `/gsd-verify-work`:** Full suite must be green
- **Max feedback latency:** 300 seconds

## Per-Task Verification Map

| Task ID | Plan | Wave | Requirement | Threat Ref | Secure Behavior | Test Type | Automated Command | File Exists | Status |
|---------|------|------|-------------|------------|-----------------|-----------|-------------------|-------------|--------|
| 07-01-01 | 01 | 1 | P7-01, P7-02 | T-07-01 | 发送前拼接且消息区不回显拼接文案 | unit + e2e | `node --test frontend/src/core/threads/hooks.test.ts` + `cd frontend && pnpm -s test:e2e --grep "DF-INPUT-008A"` | ✅ | ✅ green |
| 07-01-02 | 01 | 1 | P7-03 | T-07-02 | 附件/Skill 名来源、顺序与去重规则一致 | unit | `node --test frontend/src/core/threads/hooks.test.ts` | ✅ | ✅ green |
| 07-01-03 | 01 | 1 | P7-04 | T-07-03 | 所有发送入口行为一致，不出现分叉 | e2e | `cd frontend && pnpm -s test:e2e --grep "DF-INPUT-003|DF-INPUT-005|DF-INPUT-008A"` | ✅ | ✅ green |

*Status: ⬜ pending · ✅ green · ❌ red · ⚠️ flaky*

## Wave 0 Requirements

- [x] `frontend/src/core/threads/hooks.test.ts` — 已覆盖提交态增强文本、顺序与去重断言
- [x] `frontend/src/components/workspace/input-box.test.tsx` — 由 E2E 发送入口链路覆盖，无独立缺口
- [x] `frontend/tests/e2e/input-and-compose.spec.ts` — 已包含“消息区不显示拼接文案”回归（DF-INPUT-008A）

---

## Manual-Only Verifications

| Behavior | Requirement | Why Manual | Test Instructions |
|----------|-------------|------------|-------------------|
| 多语言文案下拼接语句可读性 | P7-01 | 文案自然性主观 | 在中文/英文 UI 下分别发送含附件+Skill消息，人工检查生成文本 |

---

## Validation Sign-Off

- [x] All tasks have `<automated>` verify or Wave 0 dependencies
- [x] Sampling continuity: no 3 consecutive tasks without automated verify
- [x] Wave 0 covers all MISSING references
- [x] No watch-mode flags
- [x] Feedback latency < 300s
- [x] `nyquist_compliant: true` set in frontmatter

**Approval:** verified 2026-04-17
